The A25 Series Warm Air Control with Manual Reset is designed to shut down fans, burners, dampers, etc., when the temperature of the sensed air becomes greater than the control er’s setpoint.
When the sensed temperature increases to the
contro ler’s setpoint, the A25’s switch wil open. Manual reset is required to reclose the electrical circuit. The A25 may be used as a high limit control in the supply air duct (or plenum) where a lockout type control is desired or required by local code.
